The following safety sign is installed at an intersection with traffic lights. Which two statements are correct? Select TWO
An unprotected left turn sign lets you turn left without a green arrow, but attaches a condition regarding oncoming vehicles (Annex 6 of the Enforcement Rule). Work out which lights count as a 'go' signal, and which of the left-turning car and the oncoming straight-moving car must not obstruct the other.
Answer: ③, ④
Explanation
This sign, with the word '비보호' (unprotected) and a left-turn arrow, means that on a go signal you may turn left carefully so as not to obstruct vehicles coming from the opposite direction (Enforcement Rule Annex 6, No. 329). You may turn left on a green light without a green arrow, but must not obstruct oncoming straight traffic, so the claim that left-turning vehicles have priority is wrong. A red light is not a go signal, so you may not turn left.
